Usage
Information
You can assign up to 256 peers to one peer group.
When you add a peer to a peer group, it inherits all the peer group’s configured parameters. A peer
cannot become part of a peer group if any of the following commands are configured on the peer:
● neighbor advertisement-interval
● neighbor distribute-list
● neighbor route-map
● neighbor route-reflector-client
● neighbor shutdown
A neighbor may keep its configuration after it was added to a peer group if the neighbor’s configuration is
more specific than the peer group’s, and the neighbor’s configuration does not affect outgoing updates.
A peer group must exist before you add a peer to it. If the peer group is disabled (shutdown) the peers
within the group are also disabled (shutdown).
